The ways in which these essays speak to the theme of mobilizing politics are multiple, as is the case with the essays in Part I of this collection in relation to the theme of politicizing mobility. Indeed, the division between the essays in Part I of this collection and those in Part II of this collection is not in any strict sense a clear-cut separation, indicative of the mutual implication of the politicization of mobility and the mobilization of politics. Nevertheless, several key themes do emerge from the essays in Part II of this volume which speak distinctively to the theme of mobilizing politics. The first key theme of the autonomy of migration – already touched upon in Nicholas De Genova’s essay in Part I – is addressed directly here in the essay by Sandro Mezzadra. By focusing on the autonomy of migration, Mezzadra brings both migrant agency as well as the relation between migrant labour and capital to the centre of our analysis of irregularity. Irregularity from this perspective is understood neither as a condition of abjection nor in terms of relations of total domination. Rather, irregularity (conceived of as unauthorized movements and activities) is addressed here in terms of the creation of possibilities for new forms of political subjectivity through mobilizations of heterogeneous coalitions. A similar interest in autonomy and the politics of migration runs through the essays by Kim Rygiel, Peter Nyers and Enrica Rigo, though in slightly different ways in each case.
